The optimal period to visit the glacial lake situated below the majestic Zanibu Peak in Phek District of Nagaland is during the post-monsoon months from October to May. This timeframe takes advantage of the relatively dry season, providing clearer skies and a more comfortable trekking experience. October to May also witnesses the magnificent transition from autumn to spring, with the landscape showcasing a vivid palette of colors and the temperature remaining pleasantly cool. More specifically, November to April stands out as an exceptionally good time, with minimal precipitation, allowing trekkers to enjoy the full beauty of the lake and its surroundings.
It's especially recommended to plan your visit either around late October to November when the post-monsoon greenery is at its peak, or during March to April to witness the blossoming of rhododendrons and orchids that Nagaland is renowned for. Daytime temperatures are comfortable, and nights are cold without being unbearable, making these times suitable for outdoor activities. However, it is crucial to be well-prepared with warm clothing and suitable trekking gear regardless of the chosen month. The area's high altitude can lead to rapid weather changes, making it essential to stay geared up for cold and windy conditions.
